Through hole resistors, also known as axial lead resistors, are one of the most common types of resistors used in most electronic circuits and equipment. They come in a variety of shapes and sizes, with different wattages and resistance values. They are small, relatively inexpensive parts, and are very simple to install and replace. The FKN5WSJR-73-120R is just one example of this type of resistor, and its application field and working principle are discussed here in further detail.

A through hole resistor is generally cylindrical in shape and comes with two metal leads that extend out through the center of the resistor. The FKN5WSJR-73-120R measures 2.5 mm in diameter, with two 1.27 mm diameter Tin-plated copper leads of 59 mm length. In this particular model, the body of the resistor is made of epoxy resin, with a resistance value of 73 Ohms, and a maximum working power of 0.125 watts. It can operate in temperatures up to +125°C, withstanding large currents up to 1.5 Amps. Because of its small size and ability to dissipate heat quickly, it is well suited for applications involving high-frequency signals, such as in RF amplifiers, high-speed circuits, and antennas.

The basic working principle of a through hole resistor is the same as other resistor types. Both ends of the resistor are connected to a positive and negative voltage source. As current passes through the resistor, a voltage drop will occur due to the resistance, as determined by Ohm’s law. The greater the resistance value of the resistor, the larger the voltage drop will be and the greater the power consumed by the resistor. The size, shape, and material of the resistor will also affect the characteristics of the resistor, such as its resistance value and maximum power dissipated. The FKN5WSJR-73-120R is a relatively low power resistor, making it suitable for many applications where power consumption needs to be kept to a minimum.

In summary, the FKN5WSJR-73-120R is an example of a through hole resistor, which can be used in applications where high-frequency signals and low power levels are present. It is a small, inexpensive part that is simple to install and replace, making it a popular choice for many electronics projects. Its resistance value and maximum working power make it well suited for its intended applications, and its ability to withstand high currents makes it a reliable option for a wide range of electronic circuits.
